Translation of grandstand in German

So we first went to look for other hotels in the area, some where horrible even though they were rated as three star hotels. In the end we bought the three day voucher at the travel agent's office.
The different monuments were located in one big compound in the center. Strangely on the same day that we have visited there the prime minister of Thailand came for a visit in the same area.
Many thanks for your letter. I am delighted to tell you that I have passed my exams and am looking forward to the next year. Meanwhile I am planning a trip to Costa Rica and some places around there.
